I've heard about a glitch in both KotOR games where you are able to get through any door (including locked ones), while they are still closed. I believe it has something to do with rapidly switching characters near the door or something of that nature. Does anyone here know how to do this? Thanks.

You can do it by switching characters rapidly, but there have been times that my PC went "ghost" and walked through the door it's self.... it was odd.... but then I couldn't get back through so I had to load an earlier game save
